Florida dengue outbreak reaches 252 cases in largest US wave in decades

Florida has recorded 252 cases of dengue fever this year in an outbreak that has become the largest in the continental United States in decades, according to The Hill. [1]

Dengue fever infects between 50 million and 100 million people globally each year, resulting in half a million life-threatening cases. The frequency of infections expanded thirtyfold between 1960 and 2010. This surge is attributed to a combination of global warming, expanded international travel, urbanization, and overall population growth. Approximately 70 percent of the 2.5 billion people living in endemic regions reside near the equator in Asia and the Pacific. Many people infected during outbreaks do not undergo viral testing, meaning some illnesses may involve coinfections or other viruses such as chikungunya. [2]

Florida possesses a subtropical to tropical climate that provides year-round warmth, although the state is susceptible to hurricanes and flooding. Low-lying plains mostly under 100 feet above sea level characterize the geography of the state, which has a contiguous coastline of roughly 1,350 miles. In 2025, Florida recorded a gross domestic product of 1.83 trillion dollars, ranking fourth in the nation. The state leads the country in the production of crops such as oranges and sugarcane, and tourism draws millions of visitors each year to its beaches and theme parks. [3]
